Hai, I am Jagan.I have completed my engineering in the field of Electronics and Communication Engineering.But i have been scheduled to work in the area of soldering the circuits,design and assembling of electronic components in my company.I think that you would have understood.I am scared that in what way that task would match my engineering study and does the job has enough scope to improve? Please guide me…..

I’m still a bit new to soldering..but i’m looking for a handy tool that will do me best (not a razor blade etc) that will do a clean job in cutting the track on a circuit board. thanks in advance

okay im only 16 almost 17 and looking for a major that suites me but i dont know what and i like fixing things and working with my hands. to get to my point i was wondering if their is a job where i can fix a lot of electronic stuff like tvs,computers,game systems and anything else with circuits in it. SO can anyone answer my question???
if someone can name a job like i discribed then they will win the best answer!!!!

I am building a mechanism for a mechanical engineering class where I need to have accurate figure of the mass’ RPM.

I plan on using infrared, and a disc with a small hole in it (rotates with the mechanism). I need the circuit to be able to count every time it "sees" the infrared light through the hole. I work for radioshack and I have access to practically everything I need to accomplish this, but I’m not a low-voltage electronic person. I am skilled at soldering and would have no problems if someone knows where i can find a simple schematic of this circuit.

If possible, I’d like a display of rotations per second (the calculations will be made using radians per second and would save a math step). That would be the slickest way to do it, but I know that would require an LCD/LED controller and will complicate it. Another way possible would be to have the circuit make a beep every time it senses light on the IR receptor everytime the light shines through, and just count it over a period of time. That’s what I would do last resort, but either way I won’t know enough of circuits to build one myself.

Any help would be greatly appreciated.
After reading what Edesigner suggested, I want to restate that I’d like to tackle this as a DIY job. I work for radioshack and everything I need for this circuit should be here.

In the essence of time, I may just have to resort to using beeps, which seems like it would be a much simpler circuit.

During the process of this I-search paper I would like to discover some things about this occupation. This includes salary, I think that the average salary for this occupation is ,000, but I am not really sure. Next I would like to learn some terms that are part of a radiologic technologist, I am particularly interested in finding out what the x-ray machine is called. It must have a more formal name. Another important thing one must know is the training and education needed to do this. I am interested in a career with a minimal amount of schooling but one that still pays a decent amount; I am hoping that an x-ray technologist has this balance. While this job may sound fun, interesting and seem like it’s for me, I would like to know if I have good traits for this occupation. If this job isn’t for me, it would be interesting to know jobs that are similar to this one.
When it comes to salary in this field, as you gain more experience you will earn more money. Also another factor of the pay of this profession is where you live. For example, in New York, which is where I intend to stay, an x-ray technologist in Elmira will make ,240 compared to someone in Nassau who will make ,510 (Radiologic technologist, Choices). The average salaries of starting X-ray technologists in the United States make ,000. If I decided I enjoyed this job and stuck with it for about four years I would make ,453. After twenty years in this career, I would be making around ,200 (Median Salary by Years Experience). Each website and book says something different so I picked the one that seemed most reasonable. Another thing that can impact your salary is what kind of a place you are working at. Working at a hospital I could earn more them if I worked in a privet practice or a firm (Median Salary by Years Experience).
The next thing I wanted to know was terms and every day words that x-ray technologist uses because conveying ideas and important information definitely is big part of this job. Also being able to explain what they mean to people who are getting the x-rays. The most interesting word I found was Bucky; this is what the tray where the x-ray film is loaded. Sadly the x-ray machine does not have an interesting name, it merely an X-ray machine (Radiologic Technologists and Technicians)
During the course of my research, I have found out about the training needed for this occupation. First, I’ve realized that the courses you take in high school can help you when applying to colleges where you plan to take a lot of one type of course. One example of this is the career I’m interested in, when training to be an x-ray technologist a lot of science classes are needed, taking as many science and biology in high school can help you during college. For being a x-ray technologist some good courses to take in high school are biology, anatomy, physics, chemistry, math, and writing and speech. A handful of these courses are required but again extra science classes will help you when applying to colleges where you plan to take courses involving a lot of science. The book Exploring Health Careers, suggests those high school courses. All the listed courses are for the most part are related, except math, writing and speech. I couldn’t find out exactly why I needed math in this career but after some thought, I think it probably has to do with setting up x-ray machines and taking measurements of breaks in patients bones. As for writing and speech classes that are suggested, conveying your ideas so that others can understand you is a daily part of this job. Speaking to people about something they do not have a great understanding of is tough enough already, then when patients are in pain and distressed it could probably get a bit more challenging. Writing in this career along with ant medical career is most likely to update files so that other professionals can read and understand them. On to college, being a radiologic technologist doesn’t require a huge amount of college. Knowing computers is an additional thing I found that was important in this line of employment, this is because working the x-ray machine includes working with circuit boards, processors, electronic equipment, computer hardware and computer software. This topic is something I could defiantly learn a lot about. Two years, or an associates degree at a technical school is needed. During these two years my class load would be heavy, some students prefer to space the courses out and go to college for 3 years (Radiologic Technologists and Technicians). Things studied during college are radiation protection, pathology, patient care procedures and medical ethics among other things. After college, you can become certified or licensed by the American Registry of Radiologic Technologists, certification will help you when applying for a job. To get this certification I would have to pass an exam on everything I learned in college (How To Be an X-Ray…). Anoth

I worked for my uncle from 99 till 2000 in his electronic shop . It wasn't a great job , but I needed the money .

But now I am trying to apply for a better job , so I can take care of my family
But i'm stuck on how to write this following in such a way that will get me an interview .

this is what I did there in his shop , i dn't remember the title . What do you think I should write as a tite?

I used multi – meters , digital oscilloscope and function generator to test digital and analog circuit . I also used a DVM ( Digital Volt Meter ) . I also know how to use a spectrum analyzers. Also routinely used common software applications such as MS Word and MS Excel MS Power Point to produce reports and graphs that was required.

I have a couple electronic pachinko machines, a Nishijin "Elfin" and a Daiichi "3-One-Model".

A friend says the knob will only work if the machines are hooked up to a cash machine. That enables a servo or stepper motor, which operates the ball-driving mechanism.

I see the connectors where the cash machine interfaces. My question is, is it a simple job of electrically tying some digital inputs high/low, or would I need to emulate a more complex communication protocol (i.e. "act like a cash machine") to get the knob to work?

Or is there some other way to enable the motor elsewhere on the circuit board. (I am an engineer, so you do not need to simplify the explanation)

Thanks in advance!
Everything works except for the knob. I can load it with balls and shoot them by manually reaching into the back of the machine and flipping the lever. The video works normally, and the machine pays out jackpots.

I think disabling the knob is for security – so the machines cannot easily be tricked into working without the cash machine in the circuit.

For this problem, my tutor said the null and alternative hpothesis is:

Ho: u=3
H1: u is not equal to three

Is that right. I am not trying to be disrespectful to him, it's just my book has a different answer, but my book could be wrond.

Problem: A manufacturer of electronic kits has found that the mean time needed for novices to assemble its new circuit tester is 3 hours, with a standard deviation of .20 hours. A consltant has made a new instructional booklet intended to reduce the time an inexperienced kit builder will need to assemble the device. In a test of the effectiveness of the new booklet, 15 novices require a mean of 2.9 hours to complete the job. Assuming the population of times is normally distributed, and using the .05 level of significance, should we conclude the new booklet is effective?

Is there a safety mechanism inside a unit that shuts off appliances if it gets wet? And if so how do I identify it to replace it. I can't find a electronic repair man to do the job. And is there a safety procedure I have to take in doing so? I would like to replace a thingamabober circuit inside my Klear Action Whitening Light Tooth Whitening System Light that was shut off when I got in wet inside my mouth. The instructions said it was to be place inside my mouth but I had a lot of slobber and it got really wet now the light wont come on. It is brand new and I don't have a option to replace it. Thanks for your input.
Thank you so much Stephen M!
And everyone else.
